1.22.24 - Congrats to the dental students who matched to residencies today 🙌 Quick Review #97 - #surgery #surgeon #doctorgallagher #oralsurgery #oralsurgeon #omfs #dentist #dentistry #dental Intraoral Vertical Ramus Osteotomy (IVRO) is a type of orthognathic (jaw) surgery. This surgical procedure involves making vertical cuts in the mandible's (lower jaw) ramus. This is performed to correct jaw misalignments. Indications for IVRO: 1. Correction of Jaw Misalignment: It's often used to correct various types of jaw discrepancies, such as retrognathism (receding lower jaw) or prognathism (protruding lower jaw). 2. TMJ Disorders: IVRO is indicated in cases where TMJ disorders cause significant pain or functional issues, and where other treatments have not been effective. 3. Facial Asymmetry: It can also be used to address significant facial asymmetry due to jaw misalignment. 4. Obstructive Sleep Apnea: In some cases, IVRO is indicated for treating obstructive sleep apnea related to jaw structure. Pros of IVRO: 1. Less Nerve Damage Risk: Compared to some other jaw surgeries, IVRO poses a lower risk of damage to the inferior alveolar nerve. 2. TMJ Relief: It can provide significant relief from TMJ-related symptoms. 3. Improved Occlusion and Aesthetics: IVRO can improve both the function and appearance of the jaw and face. 4. No Need for Jaw Wiring: Post-surgery, the jaw typically isn't wired shut, allowing for better immediate postoperative function. Cons of IVRO: 1. Relapse Potential: There's a risk of the jaw reverting to its original position. 2. Limited Movement Post-Surgery: Patients may experience limited jaw movement initially after surgery. 3. Postoperative Care: Requires diligent postoperative care, including a soft diet and possibly physical therapy. 4. Surgical Risks: As with any surgery, there are risks of infection, bleeding, and complications from anesthesia. Common Complications: 1. Relapse of Jaw Position: This is one of the more common complications, where the jaw may gradually move back towards its original position. 2. Infection: Any surgical procedure carries a risk of infection. 3. Hemorrhage: Bleeding during or after surgery is a potential risk. 4. Temporary or Permanent Nerve Damage: Although less common than in some other types of jaw surgery, nerve damage can occur, affecting sensation in the lower lip and chin. 5. Difficulty in Jaw Function: Problems with chewing, speaking, or opening the mouth can occur, usually temporarily. 6. Pain and Swelling: Common postoperative experiences, which usually resolve over time. References: 1. AO Foundation. (n.d.). AO Surgery Reference. Retrieved from https://lnkd.in/effrrBzH 2.
